Interfacing to Isaac Sim with C++

Noob question here…

I have an existing robot controller written in C++ formally developed using Mujoco for simulation… I want to try swapping Mujoco out with Isaac Sim. How can I do that? It seems that Python is the only API for Isaac Sim. The Isaac SDK eco-system is massive and a bit overwhelming. Is there any documentation as to how I would swap Mujoco out with Isaac Sim for a C++ (non-Python) application?

the C++ api is on the roadmap, but no confirm date yet. probably towards the end of the year

Are there any updates on the availability of a public C++ SDK for Isaac Sim?
